The roll-separating mechanism of existing four-roller crusher is hydraulic type.This device theoretically its outstanding advantages is that roll gap is easy to adjust, laborsaving; machine operating noise is little; be easy to realize iron protection; but expose in actual use a lot of problems; as roll gap cannot promptly and accurately be adjusted and keep; cross the problems such as iron is protected weak effect, and the hydraulic system dwell time is short, leakage of oil is serious.
Summary of the invention
In order to solve existing four-roller crusher, cross iron protection weak effect, the problems such as the hydraulic system dwell time is short, leakage of oil is serious, the present invention proposes a kind of four-roller crusher hydraulic control system, by the transformation of structure, not only solve short problem of system dwell time, and realized the automation of producing; Cross the automatic oil suction of iron when protection oil hydraulic cylinder rod chamber perfect the automatic iron protective function of crossing of equipment; Flexible pipe shock insulation has thoroughly solved on-the-spot leakage of oil serious problems.
The technological scheme that the present invention solves its technical problem employing is: this hydraulic control system comprises fuel tank, filter, gear pump, motor, pressure gauge, 2/2-way solenoid directional control valve, system relief valve, one-way valve, 3-position 4-way solenoid directional control valve, Pilot operated check valve, pressure relay, accumulator, safety valve, one-way throttle valve, synchronous hydraulic cylinder, described fuel tank connects filter, filter connection teeth wheel pump, gear pump connects respectively motor, pressure gauge, one-way valve, 2/2-way solenoid directional control valve, one-way valve connects respectively two 3-position 4-way solenoid directional control valves, 3-position 4-way solenoid directional control valve connects respectively Pilot operated check valve, synchronous hydraulic cylinder in parallel, safety valve, synchronous hydraulic cylinder connects one-way throttle valve, one-way throttle valve is Bonding pressure relay and accumulator respectively, pressure relay Bonding pressure table, pressure gauge connects Pilot operated check valve and 2/2-way solenoid directional control valve, accumulator connection safety valve, 2/2-way solenoid directional control valve connected system relief valve.
Described synchronous hydraulic cylinder connected pipes is flexible pipe.
The invention has the beneficial effects as follows: oil hydraulic cylinder rodless cavity self-closed and automatic compensation have not only solved short problem of system dwell time, and realized the automation of producing; Cross the automatic oil suction of iron when protection oil hydraulic cylinder rod chamber perfect the automatic iron protective function of crossing of equipment; Flexible pipe shock insulation has thoroughly solved on-the-spot leakage of oil serious problems.
Accompanying drawing explanation
The schematic diagram of Fig. 1 hydraulic control system;
1. fuel tanks in figure, 2. filter, 3. gear pump, 4. motor, 5. pressure gauge, 6. 2/2-way solenoid directional control valve, 7. system relief valve, 8. one-way valve, 9. 3-position 4-way solenoid directional control valve, 10. Pilot operated check valve, 1. pressure relay, 12. accumulators, 13. safety valves, 14. one-way throttle valves, 15. synchronous hydraulic cylinders.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, and this hydraulic control system comprises fuel tank 1 as shown in Figure 1, filter 2, gear pump 3, motor 4, pressure gauge 5,2/2-way solenoid directional control valve 6, system relief valve 7, one-way valve 8,3-position 4-way solenoid directional control valve 9, Pilot operated check valve 10, pressure relay 11, accumulator 12, safety valve 13, one-way throttle valve 14, synchronous hydraulic cylinder 15, described mailbox 1 connects filter 2, filter 2 connection teeth wheel pumps 3, gear pump 3 connects respectively motor 4, pressure gauge 5, one-way valve 8, 2/2-way solenoid directional control valve 6, one-way valve 8 connects respectively two 3-position 4-way solenoid directional control valves 9, 3-position 4-way solenoid directional control valve 9 connects respectively Pilot operated check valve 10, synchronous hydraulic cylinder 15 in parallel, safety valve 13, synchronous hydraulic cylinder 15 connects one-way throttle valve 14, one-way throttle valve 14 is Bonding pressure relay 11 and accumulator 12 respectively, pressure relay 11 Bonding pressure tables 5, pressure gauge 5 connects Pilot operated check valve 10 and 2/2-way solenoid directional control valve 6, accumulator 12 connection safety valves 13, 2/2-way solenoid directional control valve 6 connected system relief valves 7.
Fig. 1 is the roll-separating mechanism hydraulic schematic diagram after improving, and its principle of work and power is:
(1) oil hydraulic cylinder rodless cavity self-closed, automatic compensation; When system is suppressed to working pressure to oil hydraulic cylinder rodless cavity, when 3-position 4-way solenoid directional control valve 9 dead electricity to meta, gear pump quits work, oil hydraulic cylinder rodless cavity is by Pilot operated check valve 10 self-closed pressurizes; When oil hydraulic cylinder rodless cavity pressure is during lower than the minimum setting pressure of pressure relay, system starts ftercompction automatically; When oil hydraulic cylinder rodless cavity pressure is because crossing iron higher than pressure relay during high setting pressure, system is by 6 pressure releases of 2/2-way solenoid directional control valve;
(2) the automatic oil suction of oil hydraulic cylinder rod chamber while crossing iron protection; During work, oil hydraulic cylinder rod chamber does not seal, cross iron when protection oil hydraulic cylinder rod chamber by 3-position 4-way solenoid directional control valve 9 metas from the automatic oil suction of fuel tank 1, avoid stoping passive roll to retreat iron because oil hydraulic cylinder rod chamber produces vacuum, after iron, passive roll can automatically restore to normal operation position excessively;
(3) flexible pipe connects and can effectively isolate body vibrations; Protection hydraulic tube piece can be because of the pine leakage of oil of shaking;
(4) defect having shown without pressure when pressure 5 tables have been eliminated the oil-feed of oil hydraulic cylinder rod chamber is set up in gear pump 3 outlets; Protection passive roll hydraulic system when post-tensioning can not cause damage because can't see pressure.
Finally also the most important thing is; embodiment is to of the present invention further illustrating and unrestricted; for those of ordinary skills; can in the situation that not departing from flesh and blood of the present invention, do further conversion, and all these conversion all should belong to the protection domain of claims of the present invention.
